1 a citizen of theFrench Republic,'and residv mgT'at 'Rambonillet,'Seine et-Qise, France,

have invented 'certain new and useful Im- Vi provements "in Drivin'g'Mechanism for Tractor-'lricycles 'and"the Like, of which To it concern:

Be it known that I, BENJAMIN HOURIOUX,

:the'following isa specification.

' This invention relates to driving mechanfor tractor tricyclesand'the like, the tractors being niorejparticularly applicable to thehaulage of tilling apparatus and'a-gri cultural, implements. V

A inventionconsists in a driving mech anisrn n, which one orboth of; the track' wheels-may b zp sinveiy driven or both ma'y ,runloose.

V W Two of'carrying the invention into efiect- ,aresllustrated'by wayof example in theaocompanying drawings, in which clutching and declutching as applied to the second form of construction.

Iii the frame a of the vehicle is pivoted therod b of the supporting fork 0 of the steering Wheel (Z. The frame also carries a horizontal shaft e on the ends of which are mounted the two driving wheels 1", g, provided in the modification shown in Figs. 1, 2 and 3 with the coupling members h, i respectively, with which the couplings j, k sliding on the shaft e may be brought into engagement. These clutch members are of any known type.

The invention is characterized bythe device which allows the members j and k to be operated either simultaneously or separately at will.-

As shown in Fig. 2 each of the couplings 9', i0 is constantly acted upon by a spring on, n tending to keep it engaged with corresponding coupling members 71, 5. Which are secured 'to the wheels f, g, respectively.

Operatively engaging the sliding coupling members 7', it, are forks 0, 7) supported by arms 9, 1', respectively, which are pivoted to the frame at the points s, i The inner ends of these arms are pivotally connected to the rode;- a, a), and the other ends of these rods Y I tantalum ,Honmoux, or nAMBoUILtETfnnAno I; nam m cnr mma TRAoToR- r'mcyomsf I Specification o f LettersRatent.

- are jointedto levers a2, 3 3) mounted respectively on -the two shafts 1 and 2, the shaft 2 being arranged Within the shaft 1. Secured to'th'ese shafts are operating levers 3, 1," placed'side by side and provided with suitable dogs adapted to engage toothedvsectors '5, 6. Each ofthese levers carries at its free end a half-handle 7, 8, and projecting-laterally, atthe end of an arm, a supplementa-ry handle" 9, 10. When the levers 3, 4c are positioned side by side, that is when the two'mem-bers jand 7c are coupled with the corresponding elements it and 2', the halfhandles 7 and'8 form a complete handle which the driver may operate for simultaneous actuation of the two levers '3 and 4:.

In order to d'eelutch one or the other of f the tlrivingwhe'els separately, the" driver operates the corresponding lever 3 or i by means of the lateral supplementary handle 9 or 10. Declutching one of the driving wheels, the other remaining in engagement allows turning to take place about the declutched wheel as a pivot, the steering wheel (2 being of course suitably directed.

The device of Figs. 1 to3 is particularly suitable for chain transmissions. It may however, as shown in Figs. 4, 5 and 6 be also applied to a belt transmission. In this modification, the driving wheels f, g are loose on the shaft e and their hubs carry toothed wheels 11, 12 respectively connected by chains 13, 14 to the pinions 15, 16 mounted respectively on the shafts 17 and 18, and these shafts carry loose pulleys 20 and 22 and fixed pulleys 19 and 21. The shaft a of the motor drives an intermediate shaft 23 having drum pulleys 24, 25 mounted upon it. Belts 26, 27 connect the latter with the loose or the fixed pulleys of the shafts 17 and 18 according to the position given to the corresponding forks 0, p carried by bell-crank levers a, 1" pivoted to the frame at points 8, t. The forks 0, 79 may be operated as shown in the modification of Figs. 5 and 6, the movement of the levers instead of taking place in a plane parallel to the longitudinal axis of the vehicle taking place in a plane perpendicular to this axis.

The levers .3 and 4 are normally positioned behind one another. The lever 3 carrying the half-handle '7 is further provided in the plane parallel to the longitudinal axis,

' rear lever 4. carrying the rear half-handle 8 is provided with two lateralhandlealO. in

the plane perpendicular to the longitudinal axis. The two levers 3 and l; may berotated simultaneously or separately about an axis 28 carried by the frame to operate the forks o'and p by means of the rods 29 and 30. The forks and p may be guided by the 1 ribs 31, 32 movable in U-shaped guides 33,

34 respectively. By reversing the positions of the fast and loose pulleys on the two shafts 17, 18, the rod might be replaced by'a rod 35 indicated in chain-dotted lines in Fig. 5 and pivoted to the lower end of the corresponding lever.

Having now described my invention what I claim 'as' new and desire to secure vby Letters Patent is 1. In a traction vehicle, in combination, a

motor, an axle, 'a track wheel at each end thereof,'independent means for operatively connecting each wheel with said motor whereby either wheel, may be actuated alone i or both wheels may be actuated simultaneously, and levers operatively associated with said'mean's for controlling the actuation thereof, said levers being ositioned adjacent one another whereby the operator may simultaneously grasp the same with one 2. In' a traction vehicle, in combination, a

motor, an axle, a track wheel at each end thereof, independent means for operatively connecting each wheel with said motor whereby either Wheel maybe actuated alone of oneo taneously grasp the gripping means of "both,

levers with one hand.

3. In a traction vehicle, in combination, a motor, an axle, a track wheel at *each end, thereof, independent means for o eratively connecting each wheel with said motor 5 whereby either wheel may be actuated alone or both wheels may be actuated-simultane-u ously, and levers operatively associated with said means for controlling the actuation thereof, each of said levers being provided with a handle, whereby either one of said levers may be actuated by the operator,eacl1 of said levers being further provided with a half handle registerin with one another to form a complete hand e when said levers are so in their normal position, whereby the 0 rator may simultaneously grasp, said" N fhandles with one hand to actuate said levers, In testimony whereof I have signed my name to this specificationiIr-the presenceof 55 two subscribing witnesses. p v I BENJANHN HOUBIQUX Witnesses: V v
